Firefox Support Forum

I'm using a video as the background for my website, and Firefox's built-in PIP (Picture-in-Picture) icon for videos is displaying. I don't want it to be visible on my website. I tried using FFmpeg, but it did not work as it was mentioned by some people on Stack Overflow. I read that Firefox won't display this icon for videos in an iframe, but I don't want to use an iframe on my website. Is there any other solution?

Is there a way to permanently disable red underlining from Firefox spell check? This has only started occurring since an update to Firefox 110 (now on 112), but there seems to be no way to make it go away. I've unchecked the spelling box in preferences, and killed off things in about:config:

extensions.spellcheck.inline.max-misspellings 0 layout.spellcheckDefault 0 services.sync.prefs.sync.layout.spellcheckDefault false services.sync.prefs.sync.spellchecker.dictionary false

I'm using Mac Monterey, and have the global spell check turned off for that. This seems to be a problem specific to Firefox, as it doesn't happen in Chrome (spellcheck off) or Safari. I'd like to remove this entirely, since it's distracting to have it second guessing me whenever I'm typing. The main reason I use Firefox is that it gives me the ability to control many things, particularly in combination with UBlock, but I'm unable to make any progress in removing this persistent work disruption.

I'm using macOS (Apple MacBook) where I'm running the latest stable version of Firefox: 112.0.

Based on https://support.mozilla.org/bm/questions/1344663 I have already enabled the preference accessibility.typeaheadfind.prefillwithselection = true

But this only copies the selected text to the Find bar when I press Cmd-F. It doesn't automatically search the text. I then have to press the Return key or press Cmd-G to make it search and find the nearest match (and also update the number of matches, and update the highlighted results if Highlight All is enabled).

How can I skip the extra step and make it also search the selected text which it has copied and pre-filled in the Find bar? Is there another preference to control that? Or should I open a bug report in Bugzilla?

Here are my current settings with the keyword 'find':

   accessibility.typeaheadfind	false	
   accessibility.typeaheadfind.autostart	true	
   accessibility.typeaheadfind.casesensitive	0	
   accessibility.typeaheadfind.enablesound	true	
   accessibility.typeaheadfind.flashBar	0	
   accessibility.typeaheadfind.linksonly	false	
   accessibility.typeaheadfind.manual	true	
   accessibility.typeaheadfind.matchesCountLimit	1000	
   accessibility.typeaheadfind.prefillwithselection	true	
   accessibility.typeaheadfind.soundURL	beep	
   accessibility.typeaheadfind.startlinksonly	false	
   accessibility.typeaheadfind.timeout	5000
   browser.find.ignore_ruby_annotations	true	
   findbar.entireword	false	
   findbar.highlightAll	true	
   findbar.iteratorTimeout	100	
   findbar.matchdiacritics	0	
   findbar.modalHighlight	false	
   services.sync.prefs.sync.accessibility.typeaheadfind	true

(There's no actual feature here to fully delete the question or reply. I hope the support forum can be improved to provide such functionality.)

when you select text and right click popup "Search google for 'text marked'" , here google is your FF's default search engine, but for people in multi-lingual region would prefer to search e.g. web in the language of the selected text, which makes more sense for the results.

I wonder if FF could add this function, auto detect the text's language and search in e.g. google.de, google.cn or google.fr?

Which is like the macOS lookup, it detect the text language and point to that dictionary?

FF could be a little more intelligent, right?

Summary Reset a site or domain to be no longer associated with a Container

I accidentally assigned my search-engine domain to a container. As a result every single search I perform from the URL bar asks if I'd like to open it in the assigned container instead. I'll select 'Remember my decision, open in current tab' (the current tab being the base no-container Firefox user). Unfortunately this does nothing.

I've searched through the settings and options and I've found no option to get an overview of the domain configurations or to reset a certain site. I've read suggestions online to delete the container, but this isn't an acceptable approach to the problem.

My extensions take up a lot of space in my toolbar and I'd love to hide all of them. However - every 'solution' to the problem tells me to right click the extension straight from the toolbar and click 'Hide from Toolbar'.

I do remember this option existing, however I couldn't find it since last update and I'm assuming it was removed. Is there any way to use it again?

^ (Small note, It would also be lovely if I could add them to the Extensions add-on in the toolbar, as that would really be a better use for it other than overflow)

Please allow me to preface with I do not know how to code at all and I have found some options to make the scroll bar disappear, but with coding, and I'm hoping for an option that takes that away easily.

I don't think it is any of my extensions causing this, and I don't think it's an option in Firefox to remove the scroll bar.

Please help if possible! It doesn't disappear even when I'm watching videos on fullscreen.

Thank you.

Firefox stopped opening links in web pages like secondlife:///app/region/Kings%20Stone/224/155/22 ,WHere do I tell Firefox what application to use to handle that kind of a link?

With the upgrade to Firefox 106 on Mac, Private browsing windows open with a dark theme by default. How do I enable the light theme for Private browsing windows?

I use Private browsing at work for website testing, and the dark themed tabs / UI are much harder to read and use than with a light theme.

Hi Firefox community,

Do we have any settings in firefox where we can enable/disable dark mode in firefox browser instead of installing a plugin or addon? I am looking something that is offered within the browser instead of a plugin.

Thank you all.

I appreciate the quick reply from your support staff yesterday. I followed instructions and was able to turn off the GIFs but FOR ONLY ONE TIME. As soon as I exited Firefox, or even the current page and returned to it they were back on. How do I keep them off permanently?

Hi! I recently made the switch from Chrome to Firefox and Im liking it aside from this one thing. When Im watching a video in full screen, moving the cursor to the top doesnt pop up Macs top bar (File, Edit, ..... battery, time).

This sounds like a banality but I mainly watch videos while getting ready, working etc, and I really need to see the time! Im used to always keeping the cursor at the top to see it. I searched around in settings and forums but didnt find any fix. The only solution seems to be to not use full screen which I think we can all agree just sucks in a major way.

Im using MacOS Monterey 12.3.1 and Firefox 102.0.1. Is there a way to fix this or nah? Any info much appreciated!

Frequently when I update Firefox something stops working the way I want it to. So after the last update I disabled updates. That was a while ago (version 89) and my browser was getting pretty stale. So I backed everything up, reenabled updates, and now I have version 104.

And, of course, something is broken now. The context menus when I right click are not functioning as before. The userChrome.css is still there in the chrome folder in my profile and has the same contents. The option toolkit.legacyUserProfileCustomizations.stylesheets is set to true. But it doesn't work anymore. I added a line to change the color of the tab toolbar and that worked. So userChrome.css is being read and acted upon. But the other command (I whittled it down to just one additional command for testing) is ignored.

Here is what my userChrome.css looks like right now:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

1. context-openlinkintab { display:none!important; }
2. TabsToolbar{ background-color: #CCCCCC !important }

But the "Open Link in New Tab" still appears in the context menu when I right click a link. It didn't do this before the upgrade to 104. Did something break in between version 89 and 104 or is it some other oddity?

Any ideas?

Firefox has suddenly stopped sizing shipping labels when downloading them from Amazon and ebay. They print way too large. Changing the printer setting, size, etc does not help. It seems as though Firefox is converting them somehow. I have tried clearing the printer settings in Firefox also.
